[BUG] Plan and Explore agents are identical and serve no distinct purpose

Bug Description

Explore agent:
Explore: Fast agent specialized for exploring codebases. Use this when you need to quickly find files by patterns (eg. "src/components/**/*.tsx"), search code for keywords (eg. "API endpoints"), or answer
questions about the codebase (eg. "how do API endpoints work?"). When calling this agent, specify the desired thoroughness level: "quick" for basic searches, "medium" for moderate exploration, or "very
thorough" for comprehensive analysis across multiple locations and naming conventions. (Tools: Glob, Grep, Read, Bash)

Plan agent:
Plan: Fast agent specialized for exploring codebases. Use this when you need to quickly find files by patterns (eg. "src/components/**/*.tsx"), search code for keywords (eg. "API endpoints"), or answer
questions about the codebase (eg. "how do API endpoints work?"). When calling this agent, specify the desired thoroughness level: "quick" for basic searches, "medium" for moderate exploration, or "very
thorough" for comprehensive analysis across multiple locations and naming conventions. (Tools: Glob, Grep, Read, Bash)

"Yes, they are literally identical - word-for-word the same, including the exact same tool list (Glob, Grep, Read, Bash). This is definitely a configuration error in my system prompt. The "Plan" agent name

suggests it should be for planning, but the description is a copy-paste of the Explore agent."

The Plan agent is refusing to share its full prompt, but from its responses we can see clearly:

Plan Agent (Anthropic's):

• Purpose: "file search specialist" for codebase exploration
• Tools: Glob, Grep, Read, Bash
• Constraints: NO TodoWrite, NO Task tools
• Focus: Search and retrieval only

Explore Agent:

• Purpose: Same - codebase exploration
• Tools: Same - Glob, Grep, Read, Bash
• Identical description in my system prompt

feature-planner Agent (Yours):

• Purpose: Create implementation plans for features/bugfixes
• Tools: Glob, Grep, Read, Edit, Write, WebFetch, TodoWrite, WebSearch, deepwiki, Bash, AskUserQuestion, Skill, JetBrains tools
• Much richer toolset for planning

Conclusion:

The "Plan" agent is misnamed - it's actually just another codebase exploration agent identical to Explore. Your feature-planner is the only real planning agent.
